Greg Heffley is a scrawny but ambitious kid with an active imagination and big plans to be rich and famous – he just has to survive middle school first.

A new school year, his brother Rodrick teases him over and over and over and over again. Will Greg manage to get along with him? Or will a secret ruin everything?

The winter holidays are turning out to be especially stressful for Greg Heffley this year. After accidentally damaging a snowplow while making a snowman with best friend Rowley Jefferson, Greg worries he won’t get the new video game console he so desperately wants for Christmas. To make matters worse, he gets snowed in with his family, including his grumpy older brother Rodrick and annoying younger brother Manny.
